Over the past more than 25 years, Haixin has worked on catalytic purification technologies, especially in purification materials, ruthenium-based synthetic ammonia catalyst materials, bioenergy and chemical catalyst materials, and managed to make major breakthroughs, with some of its products being national standards and winning national awards. Its catalytic material product line provides the foundation for developing related core technologies.
Relying on its core catalytic technology advantage, Haixin has developed hydrocarbon-based biodiesel production technology and biomass direct liquefaction technology for the recycling of waste biomasses with its independently developed suspended bed platform technology and improved fixed bed process. Additionally, drawing upon its catalyst development experience and technology accumulation over the years, it has also developed the technology of bio-aviation fuel from Hydroprocessed Easter and Fatty Acids (HEFA).
hydrocarbon-based biodiesel production technology
Applying its suspended bed platform technology and an improved fixed bed process and using waste animal and vegetable fats and supporting catalysts as main inputs, Haixin produces various biomass-based products, including bio-naphtha, biodiesel and bio-aviation fuel through a series of chemical reactions such as hydrodeoxygenation, decarboxylation, decarbonylation and isomerization. With multiple advantages, such as the abundant supply of inputs, uniform reaction temperatures, lower energy consumptions, higher yield coefficients of high/low-cloud-point hydrocarbon-based biomass diesels and higher product quality, Haixin has been the largest hydrocarbon-based biodiesel supplier on the domestic market.
bio-aviation fuel (HEFA) production technology
Haixin has developed the packaged technology of turning high-cloud-point hydrocarbon-based biomass diesels into low-cloud-point hydrocarbon-based biomass diesels and HEFAs through the hydrocarbon-based biodiesel isomerization process and has built the production capacity of specialized catalysts. Its HEFA constituents meet relevant national and international standards, and Haixin has built the capacity for commercialized production of HEFAs.
The MCT suspended bed hydrogenation technology is an advanced platform technique for processing inferior and heavy inputs through high-temperature and high-pressure hydrophilic reactions. With higher yield coefficients of light oil and significantly higher quality of products, Haixin's technique is the leader across the world and a major breakthrough at home, raising the yield coefficient of light oil by 20-30% over conventional processes, including delayed coking.
Applying its MCT suspended bed hydrogenation platform technology, Haixin has independently developed the technology of biomass direct liquefaction. In this process, pulverized solid waste biomasses are first transformed into slurry and then into products, such as bio-naphtha, biodiesel, bioaviation fuel and bioasphalt, following MCT suspended bed hydrogenation and post-processing.
Low-pressure ruthenium-based ammonia synthesis technology is a major breakthrough in catalytic materials and processes, and its centerpiece is the new generation of ruthenium-based ammonia synthesis catalysts. In contrast with conventional iron-based ammonia synthesis catalysts, these new type catalysts deliver higher single-pass conversion ratios of ammonia synthesis under lower reaction pressures, significantly reduce energy consumption, slash maintenance costs and enhance safety factors.
Cobalt-based Fischer-Tropsch synthesis technology utilizes syngas generated during coal, natural gas or biomass conversion as the input to produce high-quality solvent oil and synthetic waxes through Fischer-Tropsch synthesis reaction.
Drawing on the cobalt-based fixed bed Fischer-Tropsch synthesis technology jointly developed with its partners and its independently developed key technologies such as carbonization and gasification, Haixin has developed the distributed, flexible and adaptable packaged technology of Fischer-Tropsch synthesis. The synthetic waxes produced with this technology have various special properties, including higher melting points, higher hardness and narrower fractions, thus have higher marketability.
Haixin has jointly developed with its partners the iron-based Fischer-Tropsch synthesis technology for producing α-olefin holds independent intellectual property rights. The patented technology has a technology advantage over the slurry bed process and more promising application prospects in the fine chemicals sector as molten iron catalysts produced have more stable performance, lower costs and more favorable tech-economic features.
Drawing on its independently developed suspended bed platform technology, Haixin has developed the slurry-based hydrogen sulfide removal and recycling process for recycling advanced desulfurized materials. This unique desulfurization technique has various strengths, including smaller investments, lower operational expenses and no secondary pollution, and is widely adopted in large-scale desulfurization industries, including oil and gas exploitation and coal chemicals.
